But just so u know, I don't know what ram u have, but some ram barb threads aren't both 10/32... Mostly on some wgp rams, one of the threads will be 10/32 but the other will be a diff...not allowing u to use both qevs...

Please remember, The Karnivor came with the STO ram and their QEV's which was the same ram as the stock 04' prostock. The Karnivor reached high rates of fire that would be acceptable by today's standards. Some rams have larger rod diameters which would result in a decreased forward force on the paintball along with the decreased rod end volume. The finish on the Evo/Besales rams are nice however but as far as performance, if your not shooting ungawdly rates of fire, you shouldn't notice much of a difference between rams. The addition of the QEV's will decrease cycle time no mater which ram you are using. Just make sure the thread is 10/32"
